Document Type: Journal Paper


A study of local buckling of wide-flange and box section beams subjected to stress gradients due to transverse loading is presented. The resulting eigen matrices are solved using a search technique. Buckling coefficients for typical cases are presented. Results are compared with those used for customary design procedure.
